I saw this hottie the other day at Starbucks talking on her cellphone. She smiled at me and I thought to myself, "Game on!" That was until I approached the bar and saw the band on her cellhand. Total rock block!

Similar to a cock block, a rock block is when someone or a group of people purposefully sabatoge a drug deal. Although this term has roots in the crack cocaine trade it can be used for all kinds of drug deals which go bad. Busted gang membems will sometimes cooperate with police and rock block in order to get a reduced sentence for their own crimes or they'll rock block out of revenge.

There was a bad rock block last night so now the whole group is split in 2 over tensions.
